TL;DR
A toilet flapper replacement is the swap of the rubber seal at the bottom of the tank that lifts on flush and reseals the flush valve, the usual fix for a toilet that runs intermittently or trickles around the clock. Flappers degrade from chlorinated water and drop-in tank tablets, losing their seal long before they look bad; the dye-tablet test in the tank confirms the leak.
What it means
A toilet flapper replacement is the swap of the rubber seal at the bottom of the tank that lifts on flush and reseals the flush valve, the usual fix for a toilet that runs intermittently or trickles around the clock. Flappers degrade from chlorinated water and drop-in tank tablets, losing their seal long before they look bad; the dye-tablet test in the tank confirms the leak. Matching size matters, since modern toilets split between 2-inch and 3-inch flush valves, and a silent leak here can waste thousands of gallons a month.
